Having never had a Rodenbach sour on tap before, I was delighted to find their Flemish Red and Grand Cru on tap at WF at the Domain. For those that haven't tried sours before, the Red is a wonderful start, but the Cru is a masterpiece. Makes going to Whole Paycheck all the more palatable.
For those lower carb folks out there - good beer and that lifestyle usually clash. Sours are a great alternative because they are typically left with significantly less residual sugar (hence the "sour" conversion of sugar to lactic acid). The Grand Cru is bracingly sour.
